How do you get your level 75 minion card?

Hi I am a level 84 wizard and in Avalon I was supposed to get a level 75 minion card. I would like to know how you get it I am already passed level 75 I am in Azteca now. I really want it it will really help me in Azteca .

If you look near the bottom, the spell you want is Sir Bedevere. The page I linked tells you you get it by completing a quest chain that starts with Castle of Aaauugghh, if you click on the quest the link takes you to the wiki page for that quest, it is given by Halston Balestrom in Ravenwood.
